FOUNTAINPEN.

SPECIFICATION forming part of Letters Patent No. 659,696, dated October :16, i960'.

Application filed August 24, 1899. Serial No. 728.305. (No model.)

To all w/tom it may con/cern,.-

Beit known that I, CARL J. RENz, of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Fountain-Pen, of which the following is a full, clear, and exact description.

One object of my invention is to so construct a fountain-pen that the pen may be drawn partially or entirely within the nozzle or carried out therefrom through the medium of a key at one end of the barrel to vary or entirely cut off the flow of ink.

Another object of the invention is to provide a metal feed independent of the pen to which it is applied and which may be used as an upper or an under feed, as desired.

A further object of the invention is to provide the barrel with a piston and stem, the latter having a screw connection with the barrel,and,furthermore,to construct the stem with a pen-carrying head, which serves as a valve for the socket or nozzle, whereby when the piston is moved in one direction the ink is drawn by suction into the barrel from the pen and when moved in another direction the ink is forced from the barrel to the pen.

Another object of the invention is to provide a means whereby the nozzle or socket may be screwed in position in. the barrel through the medium of the aforesaid key.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal section through the pen with the supply of ink cut off, the pen being drawn partially within the nozzle or socket. Fig. 2 is a view similar to Fig. 1, the cap having been removed and the pen being in position to write, the ink being supplied to the pen. Fig. 3 is a longitudinal vertical section through the improved peu, showing a slight modification in the construction of the barrel and illustrating the nozzle or socket as removed entirely from the barrel. Fig. 4c is a transverse section taken practically on the line 4 4 of Fig. 1. Fig. 5 is a section taken substantially on the line 5 5 of Fig. 3. Fig. 6 is a perspective view of a locking-sleeve employed in connection with the key. Fig. 7 is a detail perspective view of the key. Fig. 8 is a detail perspective View of a sleeve adapted to be tted in the barrel. Fig. 9 is a detail perspective view of the adjusting-head of the piston-stem. Fig. 10 is a perspective View of the piston. Fig. l1 is a perspective view of the washer used in connection with the piston. Fig. 12 is a detail perspective view of the pen socket or nozzle; and Fig. 13 is a perspective view, partially in section, of the pen-supporting head of the piston-stem and a feeder in position on the said head.

The barrel A of the pen is provided at its lower end with an interior thread lO, adapted to receive the upper eXteriorly-threaded portion of a pen socket or nozzle B, and this pen socket or nozzle is provided with a suitable flange 11, which enables it to be readily removed from the barrel. The said pen socket or nozzle is adapted to receive the usual cap B when the pen is not in use.

Below the ange 11 the pen-socket B is usually provided with an interior annular rib 12, having beveled upper and lower surfaces 13, the lower beveled surfaces 13 being adapted to receive a correspondingly beveled or conical surface 14, formed at the upper end of the pen-supporting head C, and when the surface 14 of the pen-supporting head engages with the inclined surface 13 in the socket or nozzle the pen-supporting head serves as a valve to effectually prevent any ink gaining access to the lower portion of the said head or the pen or feeder carried thereby. This pen-supporting head C may be provided with one or more air-vents l5, as shown in Fig.13, iffound necessary. The feeder 16 is made of Wire of suitable gage, and one of its ends is attached in any desired manner to the pen-supporting head, while the opposite end, which may be slightly flattened'and curved vand is more or less pointed, extends anyy desired distance beyond the lower end of the said pen-supporting head. The pen 17, when the feed is to be an overfeed, is passed between the feed and the supporting-head C, as shown in Figs.

1 and 2, the rear end of the pen being provided with a notch 18, which receives the inner end of the feed; but when the feed is an underfeed, as shown in Fig. 3, it engages with rel A, near the upper or outer end thereof, l

and this threaded surface receives an adjusting-head 23, which is exteriorly threaded and is secured' upon the stem 19t by a pifn; or."` the j barrel, an, externally-threaded pistonstem, a `pieten en saidM stem, and` akey mounted to equivalent of the same, asfshowrr in Figs'. l` and 2. Immediately below the adjustinghead 23 a piston 24 is located ou thesternalQ, together with a Washer 25, and these` parts are held in position by a', pin 26 or the like. The upper or outer end ofthe stem 19.r is adapted to enter a polygonal longitudinal chamber 28., formed in a key 21 which oo nstitutes the outer end of the finished peu.` This key 27 is provided with ani annular exterior rib 2S, and this rib is4 received within the inner reduced surface ot' a, sleeve; 29sy em gaging with a shoulder' 30 inthe sleeve formed by such reduction, and this sleeve 2.9- i-s screwed upon the upper end of the barrel, as shown in Figs. 1, 2, and 3. Thusitwilli be observed that the key 27, while held. to the barrel in a simple and eiective manner, is`

free to` beturned and that whenl the key is turned in onedirection,theadjausting-head 23 `Will travel down the threaded sutiace 2210i the barrel,as shown in Fig. 2toiagreate-r or less extent, and the pistone` 24 will force: the ink to the feeder 16', since the downward movement of the adjusting-head will have carried the pen-carrying head C. to the; lower portion of the nozzle or socket,` thus. opening communication` between thebarrel and the 1, all the ink, or practically all of it, will have been. removed from thc pen and i-tsf'eeder..

It is. evident. that the adjnstinghead may be` so constructed that the. pen and itsisu'p# porting-head may be drawn entirely within the nozzle should occasion demand.

Apin 32 is passed through the` pistonfstem 19 near its lower end, and this. pin extelltdis` beyond opposite sides of the stem, asshown in Fig.. 3, and is adapted to contact; with the end of the nozzle Bwhen the parts are inthe position shown in Fig., 2A and limit the out-` ward movement of the pin-head C; The pin 32 is alsoadapted, when it. is desired to replace the parts after they have been moved to the position shown in Fig. 3,120 be engaged by the; end of the nozzle B to force, the parts into position in the barrel.

I desire it to be understood that although I prefer the metal single feed shown in the .drawingsany other preferred form of feed may be substituted if found desirable.

In the form of the device shown in Fig. 3

,it Willlbeobserved that the thread adapted to receive the adjustable head js made in a sleeve 33; but the thread adapted to receive the. adjusting-heady may be made directly in the barrel or at any portion of the same.

Having thusdescribed my invention, I claim as new and desire to secure by Letters Patent'- l L. Enafonntain-pen,aninternallytlrreaded rotate on thebarrel andi with which` theA end of the piston-stem has a` sliding engagemen t, substantially as and for the purpose set forth.
